Sliding door comprises a lower frame profile (3) with an H-shaped cross-section and lateral frame profiles (4) with holding grooves having protrusions at their outer ends that narrow the opening. Elongated plate-shaped intermediate parts (10) placed on these protrusions have a width on one side corresponding to the width of the holding groove behind the protrusions and a width on the other side corresponding to the width of the lower groove of the H-shaped cross-section of the lower frame profile. In between these sides the intermediate parts have a width corresponding to the distance between the protrusions. The intermediate parts are provided with bores receiving screws. Track rollers (16) are attached to holding elements (15) inserted in the lower grooves. The holding elements are provided with an angled surface on the side facing the intermediate part and have a thread or a nut in which an adjusting screw engages which is inserted into the intermediate part. |
